【背景资料】某建筑工程，建筑面积24642㎡，地上10层，地下2层（地下水位-2.0m）。主体结构为非预应力现浇混凝土框架剪力墙结构（柱网为9m*9m，局部柱距为6m），抗震设防烈度7度。梁、柱受力钢筋为HRB335.结构主体地下室外墙采用P8防水混凝土浇筑，墙厚250mm，钢筋净距60mm，混凝土为商品混凝土。一、二层柱混凝土强度等级为C40，以上各层柱为C30。
情形1：施工过程中，施工单位进场的一批水泥经检验其初凝时间不符合要求，另外由于工期要求很紧，地下室外墙施工不得不在气温只有-3℃时进行。
情形2：钢筋过程施工时，发现梁、柱钢筋的接头采用挤压连接，有位于梁、柱端箍筋加密区的情况。在现场留取接头试件样本时，是以同一层每600个为一验收批，并按规定抽取试件样本进行合格性检验。
情形3：结构主体地下室外墙防水混凝土浇筑过程中，现场对粗骨料的最大粒径进行了检测，检测结果为40mm。请根据背景资料完成以下选项。
本工程基础混凝土应优先选用（）。 ["矿渣硅酸盐水泥","火山灰硅酸盐水泥","粉煤灰硅酸盐水泥","普通硅酸盐水泥"]
